C. V. LINDBLAD AUTOMATIC FEED MECHAISM FOR INDIVIDUAL CIGARETTE MACHINES Filed Nov. 13, 1925 2 Sheets-Sheet 2 LLA rlhis invention relates to an improved automatic feed mechanism for individual ciga rette machines, either of the paper wrapper type, or of the all-tobacco type sometimes called little oiga and it has for its main object the production of aV device designed and adapted for use in connection Vwith individual cigarette iachines of the rolling table type, sain device coinjarising means for i automatically and continuously feeding tobacco, and means for intermittently inten rupting the delivery ol' the fed tobacco,

the cigarette machine is rolling a cigfrom previously delivered tobacco. this and other objects not specifically a ned in view, the invention consists in certain constructions and combinations which will :e hereinafter fully described Iand then 'ically set forth in the claims hereunto so appended. in

the accompanying diwings, which i part of this specification and in like characters of reference intricate or like parts, Fig. 1 is a side elevai echanism constructed in accordth the invention; 9 is a plan the structure shown in l" Jig: 1; Fig. sectional elevation of tie structure a front elei l partly in section, of the structure shown in 1, .Q and 8; and 5 is a retail sectional view. on an enlarged scale, f tl e lower feed belt and side walls of the hopper.

l n carryingr the invention into effect, there is provided means for automatically and continuously feeding` tobacco from a mass of a width slightly greater than the length of the individual cigarettes to be made, and means for intermittently interrupting the :i .sry of the fed tobacco to an individual cigarette machine in connection with which the mechanism is used, in order to give time for the said machine to roll. a cigarette in a wrapper before it receives more tobacco for a succeeding cigarette. ln the best constructions conten'iplated, the interrupting' means is actuated by a movingpart of theciggarette machine. in the best constructions also,

there is provided a delivery throat to which the feeding mechanism continuously delivers tobacco, and chute walls below said throat and movable to temporarily close said throat to interrupt delivery of the fed tobacco.

These parts and means may be varied in .ill

construction withinv the lscope of the claims, for the particular device selected to illustrate the invention is but one of numerous ssible concrete embodiments of the same.

invention, therefore, is not to be restricted to the precise details of the specific structure shown and described.

Referring to the drawings, 6 indicates a hopper into which the cigarette tobacco is dumped from time to time as it is automatically and continuously fed outof said hopper by means of a forwarding belt 7 which reacts with a picker roll 8 to continuously feed tobacco into a throat l9 below said 1picker roll. lf he entire mechanism for continuously feedingA the tobacco is of the now well l-nown ln ander type, and since its specific construction lies wholly outside the limits of the present invention, a` detailed decription thereof, being unnecessary to a full uni'lerstanding of the present invention, is omitted in the interest of brevity and clearness. Y

Hinged at l0 to the front of the throat 9 a 'front chute wall 11; and hinged at v12l a lower level. than 10, is a rear chute wall The chute wall 11 is normally held in he position shown in Fig'. 3 by means of a oiled spring 11i surrouriding` the pintle on ihich said wall .is hinged at 10. The chute wall 13 is normally held in the position shown in Fig. 3 by means of a coiled spring 15 surroundingl the pintle on which vsaid wall is hinged at l2, rlie rear wall 13 carries a shoe 16 which lies in the Vpath of a cam-plate 1'? secured to the rolling' frame of the indivlual eigerette machine in connection with which the device is used, and moving withl it. This r lling; frame is indicated in full lines in retracted position, and in dotted lines in projected' position, in Figi'. 3.

lllhen the parts are in the positions shown in full lines in Fig. 3, the throat .9 is open and tobacco is falling through the chute between its walls 11 and to the pocket 18 of the chianti belt 19 of the cigarette machine. As the cam-plate 1'? moves forward, however, it engages the shoe 16, and, by means of the same, swings the rear wall 13 forward into engagement with the front wall 11 which the former pushes before it, both swinging forwardly and upwardly until, at the end of the forward Vmovement of the cainplate 17, they occupy the positions shown by the dotted lines in Fig. 3. When c: rei-192:' col-U reach this positionA the throat 9 is closed and tobacco begins to accumulate on the upper surface ot the rear wall 13, then 'forming' a closure for the throat 9. As the cam-plate i7 retreats. the springs let and l5 return the chute walls to their normal posi` tions, thus airain opening' the throat to permit the accumulated tobacco to tall through the chute to thc pocket ot the chianti belt tor another cigarette. The cycle ot opera tions is then repeated.

Valhat is claimed is:

1. nu automatic feed mechanism for inA dividual cigarette machines having a reciprocating cigarette rolling device, comprising mechanism tor automatically and con` tinuously feeding' shredded tobacco in a shower, and neans actuated by said device and alternately operating toguide the showered tobacco to device between ciga rette rolling operations and to 'ithhold it therefrom during said operations.

2. An automatic tced mechanism tor individual cigarette machines having; a reciprocating cigarette rollingdevice, comprising' mechanism tor automatically and continuously feeding' shredded tobacco in a shower, and means actuated by said device and alternately7 operating' to guide the showered tobacco to said device between cigarette rolling' operations and to withhold it therefrom duringV said operations, said means havinfT an actuating member in the path ot and controlled by a moving member ot said device.

8. An automatic 'leed mechanism tor 1ndividual cigarette machines having a reciprocating cigarette rolling device, comprising mechanism tor automatically and continuously feeding shredded tobacco in a shower, and means actuated by said device and alternately operating` to guide the show ere-d tobacco to said device between cigarette rolling' operations and to withhold it therefrom during' said operations, said means including' a tobacco delivery throat and movable chute walls opening' and closing said throat.

lIl. in automatic 'feed mechanism for individual cigarette'maehines having a renoires/i ciprocating cigarette rolling device, comp' mechanism Jfor automatically and con ;nuously feeding shredded tobacco in a shower` and means actuated by said device and alternately7 operating to guide. the showered tobacco to said device between cigarette rolling operations and to withhold it thereirom during said operations, said means including a tobacco delivery7 throat and hinged chute walls below said throat and normally lying in the path ot and actuated a moving member ot said device.

5. An automatic 'teed mechanism tor individual cigarette machines having a reciprocating cigarette rolling' device, comprising; mechanism for automatically and continuously feeding shredded tobacco in a shower, and means actuated by said device and alternately operatingto guide the showered tobacco to said device between cigarette rollingoperations and to withhold it therefrom during said operations, said means including' a tobacco delivery throat, a ont chute wall hinged to the front of said throat, a rear chute wall hinged to the rear oi said throat at a lower level than the iront wall hinge, and a shoe behind said rear wall and normally lying in the path ot' and actuated by a moving member of said device.

rin automatic 'feed mechanism for in dividnal cigarette machines having a reciprocating cigarette rolling` device. comprising mechanism tor automatically and continuously feeding shredded tobacco in a shower, and means actuated by said device and alternately operating to guide the showered tobacco to said device between cigarette rolling operations and to withhold it therefrom during said operations, said means including a tobacco delivery throat, hinge-i chute walls below said throat and normally lying in the path ot and actuated by a moving,- member of said device, and springs for returning. said walls to normal position atter displacement by said moving` member'.
